Cannot get my balance to zero!

No matter what I do, I cannot get my balance to zero on some of my tokens. For example, I have .005 ETH, and I transfer it to another wallet, I am left with a balance of .00000000000027 ETH, negative or positive. I have tried everything, and they just keep adding more zeron. One Balance got to about 22 zeros. e.g. -.0000000000000000000000000000000067
